An 84-year-old patient in an assisted living facility has a 6-month history of eating very little protein. The nurse notes decreased grip strength, frequent colds, and difficulty rising from a chair without assistance.

Assuming that all of the catabolic and anabolic pathways that feed into or out of cellular respiration are shown in the figure, you can say based the figure that:

A spaceship is designed to support animal life for a multiyear voyage to the outer planets of the solar system. Plants will be grown to provide oxygen and to recycle carbon dioxide. Since the spaceship will be too far from the sun for photosynthesis, an artificial light source will be needed. What wavelength(s) of light should be used to maximize plant growth with a minimum of energy expenditure?

The burning of methane (the chemical reaction shown below) is a spontaneous reaction. Nonetheless, when methane is exposed to oxygen, water and carbon dioxide are not always quickly formed. What is the most likely explanation for why this is the case?

There are many poisons that work by affecting cellular respiration. One such poison, CCCP, essentially pokes holes in the inner mitochondrial membrane allowing H+ ions (also known as protons) back across the inner mitochondrial membrane, dispersing the proton gradient. Would this increase or decrease the amount of ATP made by the mitochondria? Explain your answer. (2 pts) You may refer to the following diagram:

Based on the equation

In a properly-wired 110-120-volt polarized and grounded household outlet, what is the shape of the grounded slot (neutral)?
